What makes you think the Bitcoin Foundation is the "official spokesman" of Bitcoin?
Me personally, I don't think that the Bitcoin Foundation is the official mouthpiece of Bitcoin but it seems almost a certainty that anyone who does not know anything about Bitcoin and stumbles across "The Bitcoin Foundation" is going to make the assumption that they invented the protocol and have complete control over it.
It would be laughable for the Foundation (or anyone) to try to claim complete control over Bitcoin.
Whenever I explain what CoinLab does, non-Bitcoiners always ask, "So your company invented/operates Bitcoin?" and I then I explain how we're just part of a diverse decentralized ecosystem. Most people don't understand decentralized technologies, and that's just an inevitable educational hurdle you bump into with anyone just learning about Bitcoin.
I've met 2/3 of the board members, and these guys are such strong believers in Bitcoin. They know who invented it, why it's impossible for anyone to have complete control, and doubtless will be explaining these facts over and over to journalists, businessmen and regulators trying to wrap their heads around what Bitcoin is.
